Technical information

Check out the eco-design of this padded jacket!

The filling of this padded jacket is made from 70% recycled polyester fibres.
For the lining, we use a “bi-ton” dyeing process where only one thread in every two is dyed. This dyed thread is also the result of dope dyeing which incorporates the colour pigments from the initial thread manufacture to avoid the use of dyeing baths and reduce our water consumption.
This process can reduce CO2 emissions by 40% compared to traditional dyeing methods.

Additional sustainable development information

On the black MT100, khaki MT100 and blue MT100 models, the outer fabric uses a clean dyeing process known as Dope Dyeing (the thread is dyed before the yarn is woven) reducing CO2 emissions by 36%.

How warm is this padded jacket?

This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -5°C during a standardised test in a thermal chamber.
The model is wearing a synthetic long-sleeved T-shirt and a light fleece underneath. It works with a simulated 5 km/h wind.

We have also tested this model in "static" mode; the comfort temperature is +5°C in this case.

Want to know more about the wadding?

We use 100% polyester wadding (70% recycled) weighing 125 g/sqm in the body and 100 g/sqm in the sleeves and hood.

The wadding is made from silicone-coated spiral fibres that make it highly compressible and highly durable.
Despite its low thickness, it has high insulation properties thanks to the air trapped inside, and remains lightweight.

It retains its warmth even when wet.

Durable materials

This polyamide fabric that uses 20 denier thread can withstand 20,000 abrasion cycles.
Martindale test, Standard 12947-2.
Outer: 100% polyamide fabric 39 g/sqm, 20 denier.
Lining: 100% polyamide fabric 35 g/sqm, mix of 15 to 20 denier threads.

Water repellent property of component (not to be confused with waterproofing)

The water repellent property of a fabric is its ability to make water run off its surface without absorbing it.
This prevents the fabric from swelling, and keeps it lightweight and warm.
The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.

We recommend that you restore it after each wash.

PFC-free water-repellent treatment

On the Trek 100 hooded padded jacket, the water-repellent treatment is PFC-free.

PFCs are used to make fabric water-repellent, however they are toxic to the environment and people. By substituting PFCs with other technologies giving the same level of performance, we are reducing the environmental impact.

How to restore water-repellent properties?

Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric


A tear on a padded jacket can happen when trekking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the synthetic fibres from escaping.

Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded jacket using a heat-bonded patch.
